Title: Manufacture of buried type semiconductor laser device
Inventor: KASUKAWA AKIHIKO
IPC: H01L21/302
Filed: 1987-10-06
Abstract: PURPOSE:To obtain a narrow activated layer width with good reproducibility and a laser element having good burying layer by reforming a mesa profile into an almost vertical mesa profile by means of dry etching. CONSTITUTION:When preparing a buried semiconductor laser element by providing a mesa profile to a double heterojunction including an activated layer 13, the double heterojunction being buried by a burying layer of semiconductor whose refractive index is smaller than that of the activated layer 13, said mesa profile is reformed into an almost vertical mesa profile by means of dry etching. For example, an n-type InP clad layer 12, a GaInAsP activated layer 13, and a p-type InP clad layer 14 are grown on an n-type InP substrate 11, and the part thus grown is etched by a reactive ion beam etching as far as to the n-type InP clad layer 12. Then a p-type InP current blocking layer 16 and an n-type InP current blocking layer are grown by separating a resist 18, and a p-type InP clad layer 14 or the like are grown by separating an SiO2 layer 15.

Title: Structure of sheet cassette
Inventor: OYABU KEIJI
IPC: B65H1/26
Filed: 1987-10-08
Abstract: PURPOSE:To miniaturize a installation space by providing a carrier guide, which is guiding sheets delivered from another cassette to a discharging part of sheets delivered from a sheet housing cassette, on the sheet housing cassette. CONSTITUTION:A sheet carrier mechanism 3 composed of a guide plate is provided on a sheet cassette 1. Sheets discharged from the cassette 1 are discharged from a discharging part 34 to a device main body 21, and the sheets discharged from a sheet cassette 2 provided at the lower side of the cassette 1 are discharged from the part 34 passing through a carrier guide 3 of the cassette 1. The compatibility of the cassettes 1 and 2 is possible by providing a guide same as that of the mechanism 3 to the cassette 2. Consequently, the miniaturization can be possible and also the restriction in a attaching and detaching direction of a cassette is eliminated since a carrier mechanism is not provided on the body 21 side.

Title: Adjustment controlling system
Inventor: NAKANE RINTARO
IPC: G05B13/02
Filed: 1998-09-07
Abstract: PROBLEM TO BE SOLVED: To obtain an adjustment controlling system which enables optimum adjustment and controlling with good adjustment efficiency by controlling in such a manner that adjustment is repeated till each detected controlled amt. reaches within a specified allowance when adjustment and controlling are not previously experienced. SOLUTION: In this system, controlled variables from plural sensors are inputted, and when deviations of all controlled variables are within the allowance, the system judges 'YES', and if not, it judges 'NO' (ST12). After the system determines 'NO', whether success experience by learning is present or not is judged (ST13). When there is no experience, the operation amt. is determined by an adaptive controlling method (ST15). Then operation is carried out according to the operation amt. (ST16). Thus, the obtd. adjusting and controlling system realizes ensured convergence and decrease in controlling times by determining the operation amt. by selecting between the feed back control which ensures convergence such as adaptive control and the control pattern of learning control.

Filed: 1999-09-07
Abstract: PROBLEM TO BE SOLVED: To obtain a waveguide structure of low damages and high working accuracy by performing a reactive ion-etching as well as low damage etching for providing a overhung type waveguide. SOLUTION: A etching (RIE method) is performed halfway through a p-type InP ohmic layer 106 and a p-type InGaAsP clad layer 105 to provide a ridge-like waveguide 108. With phosphor based etchant, the p-type InGaAsP clad layer 105 comprising pn joint and a non-doped InGaAs light-absorbing layer 104 are etched sequentially. Since the ridge-like waveguide 108 is formed by RIE method with the configuration, a high-accuracy work is performed. Furthermore, the p-type InGaAs clad layer 105 and the InGaAs light-absorbing layer 104 are etched with a chemical liquid giving very little damage, since no joint is damaged for reduced leakage current.
